🧠Researchers successfully trained sparse autoencoders with 34 million features on Claude 3 Sonnet, demonstrating that dictionary learning methods can scale to production-grade language models. The extracted features show interpretability across languages and modalities, identify harmful behavioral patterns like deception and bias, and enable direct steering of model outputs—though significant limitations remain in feature completeness and validation rigor.
